Let's just agree to disagree. We both hold positions based, at least in
part, on many years of experiences.

I did not say that hex-crimp fittings WILL cause issues, I said they COULD
cause issues.

As for the knot/sweep thing; no need. I have already seen the results.

years. I have found that, if it buzzes out OK at DC, it will
generally be
OK at RF.
Ian.

With all due respect, that's a rather frightening position to maintain.
I've had to replace both .750 and .500 because of dings. Complaints were
that certain channels were out. A couple of years ago I had to replace a
4 foot piece of RG 6 inside a wall (splitter to outlet) that had the
attenuation of a 100 foot cable. 950MHz to 1450MHz worked (though not
near as well as it should have), but the rest of the bandwidth up to
2200MHz didn't work at all. Electricians had greatly exceeded the minimum
bend radius when they made up the outlet.

DC does not necessarily mean that RF will work, nor does RF necessarily
mean that DC will work.


Ed, I'm sure what you say is true. However, one-off moderate mismatches
(or even repeated moderate mismatches which are buffered by attenuation),
such as might be caused by the use of poor quality connectors, should not
cause a failure of service unless the service would have been marginal if
the connectors were good.

As for bends in cable, if you can, tie a loose knot in a piece of coax,
run a wideband sweep through it, and observe the output. Now pull the knot
tight. Let me know when the output starts to be affected.

Let me say again, I'm not advocating sloppy practices and poor
workmanship. Manufacturers' specs and industry standards should always be
adhered to. This avoids endless truck-rolls (God - I hate that
Americanism!) to the 1% of customers where some bright spark has cut one
corner too many. But, especially in the amateur world, we should maybe not
worry too much about using things which industry has rejected, often for
reasons which have absolutely no impact on what we are trying to do. So
I'm NOT throwing out my stash of crimp and screw-on F-connectors!

Ian.
